Tripodichthys
''Tripodichthys'' is a genus of marine ray-finned fish belonging to the family Triacanthidae, the triplespines or tripodfishes. The three species in this genus are found in the Indian Ocean and the western Pacific Ocean in shallow water over soft substrates. Taxonomy ''Tripoichthys'' was first proposed as a genus in 1968 by the American ichthyologist James C. Tyler with ''Triacanthus blochii'' designatedas its type species.''T. blochii'' had originally been described in 1852 by the Dutch ichthyologist Pieter Bleeker with its type locality given as Singapore. ''Tripodichthys'' is vlassified within the family Triacanthidae and, in 1968, Tyler classified this family within the suborder Triacanthoidei alongside the Triacanthodidae. The 5th edition of ''Fishes of the World'' classifies the Triacanthoidei as suborder of the order Tetraodontiformes. Species ''Tripodichthys'' currently contains the following three valid species: * '' Tripodichthys angustifrons'' Hollard, 1854 (Bl ...

Triacanthidae
Triacanthidae, the triplespines or tripodfishes, is a family of marine ray-finned fishes belonging to the order Tetraodontiformes, which also includes the pufferfishes, boxfishes, filefishes and related groups. The family is made up of four extant genera and three extinct genera which are known from fossils. Taxonomy Triacanthidae was first proposed as a family in 1859 by the Dutch physician, herpetologist and ichthyologist Pieter Bleeker, and, in 1968, James C. Tyler classified it within the suborder Triacanthoidei alongside the Triacanthodidae. The 5th edition of ''Fishes of the World'' classifies this as suborder of the order Tetraodontiformes. Genera Triacanthidae contains the following extant genera: Characteristics Triacanthidae triplespines's, like their relatives the triggerfishes and the filefishes first ray of the dorsal fin is formed to a spine. Further, they have two spines in place of their ventral fins. They have sharp and heavy teeth, which they use to eat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Order (biology)
Order () is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follow consist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Congener (biology)
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphology (biology), morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other Hominini, hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival ...

Triacanthus Biaculeatus
''Triacanthus biaculeatus'', also known as the short-nosed tripod fish, black-finned triple-spine, blacktail tripodfish, hollow-snouted tripodfish or silver tripodfish, is a species of marine ray-finned fish belonging to the family Triacanthidae, the triplespines or tripodfishes. This species is found in the Indo-West Pacific region. Taxonomy ''Triacanthus biaculeatus'' was first formally described as ''Balistes biaculeatus'' in 1786 by the German physician and naturalist Marcus Elieser Bloch with its type locality given as the Indian Ocean. In 1817 Lorenz Oken classified ''B. aculeatus'' in the new monospecific genus '' Triacanthus'', so this species is the type species of the genus ''Triacanthus'' by monotypy. This genus is classified in the family Triacanthidae within the suborder Triacanthoidei alongside the Triacanthodidae. The 5th edition of ''Fishes of the World'' classifies the Triacanthoidei as suborder of the order Tetraodontiformes. Etymology ''Triacanthus biac ...

Marcus Elieser Bloch
Marcus Elieser Bloch (1723–1799) was a German physician and naturalist who is best known for his contribution to ichthyology through his multi-volume catalog of plates illustrating the fishes of the world. Brought up in a Hebrew-speaking Jewish family, he learned German and Latin and studied anatomy before settling in Berlin as a physician. He amassed a large natural history collection, particularly of fish specimens. He is generally considered one of the most important ichthyologists of the 18th century, and wrote many papers on natural history, comparative anatomy, and physiology. Life Bloch was born at Ansbach in 1723 where his father was a Torah writer and his mother owned a small shop. Educated at home in Hebrew literature he became a private tutor in Hamburg for a Jewish surgeon. Here he learned German, Latin and anatomy. He then studied medicine in Berlin and received a doctorate in 1762 from Frankfort on the Oder with a treatise on skin disorders. He then became a ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Etymology Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the ...

Caudal Fin
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles. Fish fins are distinctive anatomical features with varying structures among different clades: in ray-finned fish (Actinopterygii), fins are mainly composed of bony spines or rays covered by a thin stretch of scaleless skin; in lobe-finned fish (Sarcopterygii) such as coelacanths and lungfish, fins are short rays based around a muscular central bud supported by jointed bones; in cartilaginous fish (Chondrichthyes) and jawless fish (Agnatha), fins are fleshy " flippers" supported by a cartilaginous skeleton. Fins at different locations of the fish body serve different purposes, and are divided into two groups: the midsagittal ''unpaired fins'' and the more laterally located ''paired fins''. Unpaired fins are predominan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelvic Fin
Pelvic fins or ventral fins are paired fins located on the ventral (belly) surface of fish, and are the lower of the only two sets of paired fins (the other being the laterally positioned pectoral fins). The pelvic fins are homologous to the hindlimbs of tetrapods, which evolved from lobe-finned fish during the Middle Devonian. Structure and function Structure In actinopterygians, the pelvic fin consists of two endochondrally-derived bony girdles attached to bony radials. Dermal fin rays ( lepidotrichia) are positioned distally from the radials. There are three pairs of muscles each on the dorsal and ventral side of the pelvic fin girdle that abduct and adduct the fin from the body. Pelvic fin structures can be extremely specialized in actinopterygians. Gobiids and lumpsuckers modify their pelvic fins into a sucker disk that allow them to adhere to the substrate or climb structures, such as waterfalls. In priapiumfish, males have modified their pelvic structures into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
